Real Time as a Constraint
Strict or Strong real-time is a system that is constrained to analyzing and responding
as events are occurring in time. Biological brains operate in strict real-time.
Unlike our conventional mathematical models, biological neural networks do not have the luxury of operating outside of the linear flow of time. They must function in real-time, and therefore, in order to properly respond, they are designed to commit, as soon as they can, to what is normally a fairly reliable perception/interpretation of reality.
